ABSTRACT:
A passenger transportation system, such as an escalator or moving walk, contains a circulating band, a driving station, and a reversing station. The driving station is arranged in the area of a first end of the passenger transportation system and has a slave control unit. The reversing station in the area of a second end of the passenger transportation system has a master control unit. For the purpose of exchanging data, the master control unit and the slave control unit are connected together by a data bus. The slave control unit has a first printed circuit board on which is mounted a first set of electronic components and which serves to transmit to the master control unit data concerning the functioning of the passenger transportation system. The master control unit has a second printed circuit board on which is mounted a second set of electronic components and which serves to analyze the data and control of the passenger transportation system. The first and second boards are identically constructed and may have identical sets of electronic components.
